Social emotional learning (SEL) is mainly about appreciating social and emotional factors and learning life skills. SEL can be divided into five categories, including how to deal with oneself, others, and relationships, and work in an effective manner. SEL helps people recognize emotions and learn how to manage them. Taking non-native English language classrooms as examples, this paper discusses how English learners performance changed when they engaged in diverse SEL experiences. Based on literature reading and analysis, this research indicates that the usage of SEL can actively affect teaching efficiency and improve learners academic achievement. SEL can entirely improve English learners interest and motivation in learning and support learners relaxed emotions. It also promotes communication among students, which allows more students to participate in teaching activities and results in better teaching efficiency. Efficient teaching and classes make students accept more professional knowledge and get better results than traditional teaching methods on exams.
